Abstract

The nonleptonic two-body $B^{*}$ $\to$ $D ˉ D$ weak decays are studied phenomenologically with the perturbative QCD factorization approach. It is found that the $B_{s}^{* 0}$ $\to$ $D_{s}^{-} D_{s}^{+}$ , $B_{d}^{* 0}$ $\to$ $D_{d}^{-} D_{s}^{+}$ , and $B_{u}^{* +}$ $\to$ $D ˉ_{u}^{0} D_{s}^{+}$ decays have branching ratios $≳$ $1 0^{- 9}$ , and might be promisingly measurable at the running LHC and forthcoming SuperKEKB experiments in the future.
